1. A method for generating synthetic images, each image simulating an image of an individual acquired by a vehicle interior camera, the method being implemented by a computer and comprising:
generating a plurality of models of individuals, each model of the plurality of models of individuals comprising a three-dimensional representation of an individual's head;
receiving a set of variable parameters and a probability distribution associated with each parameter of the set of variable parameters, the set of variable parameters relating to at least one of an environment of a corresponding model of an individual and a posture or a position of the corresponding model of the individual in relation to the environment, wherein at least one parameter of the set of variable parameters relates to the posture or the position of the individual in an interior of the vehicle, characteristics of the vehicle interior camera, or an image acquired by the vehicle interior camera;
receiving at least one parameter of the set of variable parameters, the at least one parameter relating to characteristics of the vehicle interior camera, including at least one of:
a position and/or an orientation of the vehicle interior camera,
a contrast level,
a blur level,
a camera exposure, or
a noise level;
generating a set of configurations, each configuration corresponding to a combination of values or states taken by each parameter of the set of variable parameters, such that the set of configurations is representative of the probability distribution associated with each parameter of the set of variable parameters;
generating, for each corresponding model of the individual, a set of images simulating images of the corresponding model of the individual acquired by the vehicle interior camera, where each image of the set of images corresponds to a configuration generated for a corresponding parameter of the set of variable parameters, and where each image of the set of images further comprises three-dimensional positions of a set of points characterizing the individual's head; and
storing all of the images in a memory.
